A good start is to read the free and available military standards regarding Aircrew station design.
MIL-C-6781 : CONTROL PANEL, AIRCRAFT EQUIPMENT, RACK OR CONSOLE MOUNTED
MS25212 : CONTROL PANEL, CONSOLE TYPE, AIRCRAFT EQUIPMENT, BASIC DIMENSIONS
MS25213 : CONTROL PANEL, CONSOLE TYPE, AIRCRAFT EQUIPMENT, TYPICAL INSTALLATION
MIL-DTL-7788 : PANELS, INFORMATION, INTEGRALLY ILLUMINATED
MS25212/MS25213 have drawings like the ones you request. They state that the nominal width of a type I standard panel shall be 5 3/4" 146.05 mm, and that the length of a type I panel shall be a multiple (between 3 and 24) of 3/8" 9.525 mm. They also state that the distance of the fastener holes center from the (nominal) width edges of the panel shall be .1925" ~4.9 mm, (c/c 5,365" ~136.3 mm), and from the height edges .562" ~14.3 mm (c/c multiple of 3/8" 9.525 mm).
Type II control panels are designed for specific purposes where one or more dimensions or features to qualify for being type I control panel cannot be used. Type II control panels shall be similar to type I control panels in all practicable aspects.
Regarding Boeing and Airbus the question is a bit harder. Both appears to derive their design from the military standard but to varying degree. So seems for example Boeing to be using a double standard width overhead center panel of 11 1/2", while Airbus are using a slightly larger dimension of (measured) 325 mm. Thou both are using the same (Dzus/DFCI) quarter turn fastener systems giving the length of the panels.
